Self-evidently, it was not Luther's opinion that instruction or memorizing should end here. In the Preface to the Small Catechism he says: "In the third place, after you have thus taught them this Short Catechism, then take up the Large Catechism, and give them also a richer and fuller knowledge. Here explain at length every commandment, petition, and part with its various works, uses, benefits, dangers, and injuries as you find these abundantly stated in many books written about these matters." (535, 17.) Then, as Luther often repeats, Bible-verses, hymns, and Psalms were also to be memorized and explained. Nor did he exclude the explanation of the Small Catechism from the material for memorizing. For this very reason he had written the Small Catechism in questions and answers, because he wished to have it learned, questioned, and recited from memory. "However," says Luther in the Large Catechism "for the common people we are satisfied with the three parts, which have remained in Christendom from of old." (575, 5.) As far, then, as the material for memorizing is concerned, Luther certainly did not demand more than even the least gifted were well able to render. 94. Memorizing to Serve Understanding. The second charge, that Luther attached no special importance to the understanding of what was memorized, is still more unfounded. The fact is that everywhere he was satisfied with nothing less than correct understanding. Luther was a man of thought, not of mere sacred formulas and words. To him instruction did not mean mere mechanical memorizing, but conscious, personal, enduring, and applicable spiritual appropriation. Says he: "However, it is not enough for them to comprehend and recite these parts according to the words only, but the young people should also be made to attend the preaching, especially during the time which is devoted to the Catechism, that they may hear it explained, and may learn to understand what every part contains, so as to be able to recite it as they have heard it, and, when asked, may give a correct answer, so that the preaching may not be without profit and fruit." (579, 26.) In the Preface to the Small Catechism, Luther instructs the preachers: "After they [the children] have well learned the text then teach them the sense also, so that they know what it means." (535, 14.) Correct understanding was everything to Luther. Sermons in the churches and catechizations at home were all to serve this purpose.
